We are going to continue working on this issue, in the meantime please edit your PokerTracker.cfg file with any text editor and in the section:
[General]
add the line:
Community=N
If you don't see that section, add it in the bottom so it would look like:
[General]
Community=N
Then save the file and restart PT4 and that should get everything working for you until we can release 4.10.3. You can find the PokerTracker.cfg file in PT4 by clicking File -> Open User Data Folder and going into Config.
Edit: Fixed the flag.
